Issued to US Naval Aviation and key units in every branch of the Armed Services, the M11 is proud to serve. The Sig Sauer M1-A1 has been upgraded for civilians with a stainless steel slide, a short reset trigger, and flush fit magazines. The M11-A1 variant has the same phosphate coated internals, SIGLite night sights, and Mil-Std UID label of the standard-issue M11. This Desert version features Flat Dark Earth coated alloy frame and stainless steel slide.
